Hello everybody!
I am a Linux admin trying to move my mail
system based on qmail to the software which is more spam-protected:
exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot
from src.rpm (for fc4). During
the testing stage I've discovered two troubles:
1) the problem with deliver (...I'm not sure it's a really bug). Here
is relevant part
of my /var/log/messages :
-------
Jan 3 10:40:37 serge deliver(serge at test.net): auth input: serge at test.net
Jan 3 10:40:37 serge deliver(serge at test.net): auth input:
home=/var/spool/mail/test.net/serge/
Jan 3 10:40:37 serge deliver(serge at test.net): auth input: uid=500
Jan 3 10:40:37 serge deliver(serge at test.net): auth input: gid=12
Jan 3 10:40:37 serge deliver(serge at test.net): setuid(500) failed:
Operation not permitted
-------
-- my system is fc4 based Linux. uid/gid are according to
/etc/dovecot-sql.conf :
user_query = SELECT maildir AS home, 500 AS uid, 12 AS gid FROM mailbox
WHERE username = '%n@%d' AND active='1'
I was trying to
chown 500.12 /var/spool/mail -R , chmod u+s ...etc, but it does
not helps. Please, help. I don't want another MDA, people adviced me
dovecot as good and well tested solution.
I have already spent about two work days to configure and test it...
2) Because of mentioned above problem deliver generates a bounce
message for exim, and
here is a bug with e-mail in the header.
It was taken "as is" from the queue of Exim -- have a look at
"Return-path:",
"envelope-from" and "Sender:" Because of these errors exim
can not
deliver the message back
to sender. It freezes it, ...trying again, ...freezes ... etc...

Test message body.
----------------------------------------------------------
As for POP3 with dovecot, it seems working OK. Dovecot generates
mail directories
according to the user data returned by SQL, and creates index files
proper way - everything
with given uid.gid = 500.12 ...
If you will need some extra piece of information, or my configs or
logs -- please feel
free to ask for it.
Any kind of help: advices, URLs, patches, etc.., are welcome.
I badly need to bring up this new system as soon as possible.
Thank you in advance.
Best regards,
Serge

[Dovecot] Dovecot's deliver trouble (...probably bug?)

Either that or deliver is being run as user with insufficient rights. You shouldn't have to chmod the mail store, the delivery program assumes the appropriate credentials. At least that is how I understand it. Hope this helps, Dominic
